All Snakes are Poisonous
An Australian researcher has discovered that all snakes have poisonous venom, including pet snakes that are considered harmless. Bryan Fry says, “We even isolated from a rat snake, a snake common in pet stores, a typical cobra-style neurotoxin, one that is as potent as comparative toxins found in close relatives of the cobra.”
Fry discovered this by studying the evolutionary history of venomous snakes. He wanted to find out when snakes developed this means of protection and found that it only developed once, about 60 million years ago, which is millions of years earlier than scientists previously thought. This was before the snakes we think of as non-venomous arrived on the scene, meaning that all snakes actually contain dangerous venom.
